How does the brain process perceptual errors?
In a study carried out by Pablo Rodríguez-San Esteban and Ana Chica (CIMCYC), together with Pedro Paz-Alonso (BCBL), participants were presented with a divided attention task, in which they were asked to attend to two stimuli at the same time and give two different responses, thus overloading the capacity of their attentional systems to provoke these illusions. In addition, participants were inside the MRI scanner to record how their brains functioned while doing the task.
